WebOct 25, 2024 · You can also use the function to divide a Numpy array by a scalar value (i.e., divide a matrix by a scalar). And you can use it to divide a Numpy array by a 1-dimensional array (or smaller array). This is similar to dividing a matrix by a vector in linear algebra. The way this is implemented in Numpy is with a technique called “broadcasting.” WebActually, repeated addition of a matrix would be called scalar multiplication. For example, adding a matrix to itself 5 times would be the same as multiplying each element by 5. On the other hand, multiplying one matrix by another matrix is not the same as simply multiplying the corresponding elements. Check out the video on matrix multiplication.
